Embodiment Construction

[0078] The present invention will be described in detail below in conjunction with various embodiments shown in the drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

[0079] In an embodiment of the present invention, the method and device for the unified forwarding path of OAM messages and data messages in an MPLS-TP network are mainly based on the MPLS data processing method, and are compatible with the sending of MPLS-TP OAM messages, so as to realize MPLS-TP OAM messages and Data module unified forwarding path.

[0080] The MPLS label (MPLS label) part of the MPLS data packet generally has three operations, PUSH (push), POP (pop), and SWAP (exchange). PUSH is used to push the MPLS label of the message, that is, push one or more MPLS labels before the original three-layer Payl...

Abstract

The invention provides an OAM (Operation Administration and Maintenance) message and data message uniform transmission path method and device in an MPLS (Multiple protocol Label Switching)-TP (Transport Profile) network. The OAM message and data message uniform transmission path method comprises the following steps of: carrying out various treatment manners, such as analyzing, searching and judging, on input data messages; correspondingly packaging an MPLS-TP OAM message according to the detected data messages, and marking the desired same treatment manner of the data message on the OAM message; carrying out queue treatment on the processed data message and the OAM message; and correspondingly editing the processed data message and the OAM message. Therefore, the OAM message and the data message which are processed are subjected to the same edition operation by using a uniform path, so that the resources of a packet processing chip (Application Specific Integrated Circuit) can be saved; the cost can be reduced; and the using efficiency of the chip can be improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and a device for a unified forwarding path of OAM messages and data messages in an MPLS-TP network. Background technique [0002] MPLS-TP (Multi-Protocol Label Switching Transport Profile, Multi-Protocol Label Switching Transport Profile) is a connection-oriented packet transport network (Packet Transport Network, PTN) technology developed on the basis of MPLS. As a key technology in MPLS-TP network, OAM (Operations, Administration and Management) technology undertakes the functions of error detection, error location, and error reporting, and timely informs the system to switch data channels. However, as the packet processing chip at the core of the PTN equipment, there is no specific implementation method for whether MPLS-TP OAM packets and data packets can use a unified forwarding path. [0003] Therefore, it is necessary to provide a method and device f...
